keyboard

问题 I want to know the default keyboard chosen by the user in Android. I know I can access the list of enabled input methods using the InputMethodManager , but I want to know which one is the user currently using. So far, I've tried to get the current input method subtype: InputMethodManager imeManager = (InputMethodManager) getApplicationContext().getSystemService(INPUT_METHOD_SERVICE); InputMethodSubtype subtype =imeManager.getCurrentInputMethodSubtype(); But this object only seems to give me

问题 For my subclassed RichTextBox class, I can capture, suppress the default behaviour of and re-purpose Ctrl+Shift+#, as long as # is between 1 and 9. For Ctrl+Shift+0, I can't. I have experimented with ProcessCmdKey in the form class and onKeyDown and PreProcessMessage in the control class. Here is sample code meant for the control class that should suppress Ctrl+Shift+0 but does not: public override bool PreProcessMessage(ref Message msg) { bool cancel = false; int vKeyCode = (int)msg.WParam;

问题 I've written a powershell script which displays a form using System.Windows.Forms . I've already disabled the control box and all other ways that this form can be closed via the mouse. But I can't find a way of preventing the form closing by pressing Alt + F4 . i.e. Code snippet looks like this: [void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms") [void] [System.Reflection.Assembly]::LoadWithPartialName("System.Drawing") $objForm = New-Object System.Windows.Forms

问题 im trying to create a custom macro program in C# and I want to know how I can create a low level keyboard hook. I have looked around and have found some but i do not understand how they work or how i can customise it :/ can anyone show me how I can create a keyboard hook that basically does: once any key is pressed, the int keycode is set to a method (i think the VK code is what i need?) the exampels i find online seem too complicated for that :/ Thanks :) 回答1: A Simple C# Global Low Level

问题 I've been asked to develop a new application that will work along side the existing one. Both application will wait for a barcode reader input. I don't want our operator to scan a barcode twice: once for the existing application (16bit - clipper, no sources) and once for the new application. To solves this issue I've decided to use a low-level keyboard hook (written in Delphi). It looks perfect since 2 applications will need the barcode reader input and that my application will not be focused

问题 I am trying to move textfields up while showing the keyboard. I am doing login screen in react native application, So, I have added Scrollview . But, Its scrolling for all devices. But, I need only for iPhone 5s device only. Even I tried with KeyboardAvoidingView , But, due to this entire data is overlapping. Any suggestions to avoid this issue? 回答1: You have to use KeyboardAvoidingView but not with scrollview because scrollview does not have a height. If you have to use KeyboardAvoidingView
